You are right. And I admit it, my suggestion was quite extreme lol but according to what you say, besides making it public I think they should then modify the group rules. Let's see if they take them more into account over there, besides asking for only one post a week like they do on Vibes.
It is not to compare both communities, I say it is because they also have a lot of traffic of users who interact and had to take that measure to prevent them from monopolizing the rewards. It's just a matter of taking the example or failing that, talking to someone from another community to see what they could suggest as a solution, who knows how to do it from your same point of view and authority.
I am just one of the many users here in Hive where one of my favorite communities is this one, anyway, I hope my words have been supportive, whatever decision you make, I will be aware of it. Thanks for sharing this news. 💕
